BAG-

TIE.

SPECIFICATION forming part of Letters Patent No. 349,300, dated September 21, 1886.

Application filed March 6, 1886. Serial No. 194,241. (No model.)

To all whom it may concern.-

Be it known that I, ALFRED H. BRowN, a resident of Frceport, in the county of Stephenson and State of Illinois, have invented certain newand useful Improvements in Bag-Ties; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in bag-ties, its object being to produce a cheap, simple and effective device adapted to fasten one end of a cord permanently to the bag fabric, and to receive and retain, by friction alone, the normally free end of the cord.

The construction and operation of the device are fully described in this specification, and

shown in the accompanying drawings, in which Figure 1 is a side View of the device seen upon a portion of the bag; Fig. 2, the same device revolved one hundred and eighty degrees in a vertical plane; Fig; 3, an enlarged section on the line x 3 Fig. 1; and Fig. 4, an enlarged view of one wall of the groove with the fastening position of the string end indicated by dotted lines.

The construction of my device is fully shown in the drawings. In Figs. 1,2, 3 the parts 1 2 3 are circular plates or disks, the disk 3 being on the inside and the disks 1 and 2 upon the outside of the bag fabric 9. The disks are rigidly connected with each other and attached to the bag by a screw, 5, passing centrally through each of the; three plates, and also throughthe bagwall 9. The end only of the screw'is threaded, so that it may engage with the disk 3, but not with the disks 1 and 2, and the plate Sis thickened in the middle to give greater strength of engagement with the screw. One end of the string, 7 8, Figs. 2 and 3, lies bet-ween the plate 2 and the outer surface of the bag, where it is compressed and firmly retained by the action of the screw 5. In Fig. 2 the bag, which would hide the string and the plate 2, is omitted. The adjacent faces of the plates 1 and 2, Fig. 3, are slightly conical. in gene 'al form of surface, and are both provided with. narrow annular radially-corrugated contact-faces 11,. Fig. 4-, surroruiding the screw 5,

4 or the aperture therefor, and the outer margi nal surface -of each disk curves outward.

hen the disks are properly united by the screw, the coacting corrugated faces 11 prevent relative rotation of the disks, and they formv together a solid plate, havingin its margin a deep and narrow Vshaped groove, slight- 1y rounded at its narrowest part or bottom, and somewhat flaring at its mouth or open edge. The faces of the working portion ofthe groove make an acute angle, their inclination being such that a cord pressed between them is held firmly by its friction against their surfacus. This anglo may vary somewhat, according to the character of the material of the grooved plate, the necessary anglein any case being the angle of repose of two bodies, one made up of cord or fiber and the other of the material of the grooved plate.

In operation, the device being attached to thebag, as indicated, the free endT of the cord is passed around the gathered mouth of the bag in the usual manner, and the portion still remaining free is drawn. with some force into the groove 10, and carried around therein through any desired angular space great-er or less than three hundred and sixty degrees, and the tying or securing is complete.

Fig. 4 illustrates the position of the string upon the face of the plate 2 when carried through nearly three hundred and sixty de grees, or to a distance giving ample security for bags filled with heavy grain. If the end 7 of the cord be carried still farther, so as to pass the part 7 7, the strongest cord may be broken by tension upon the part 7 without causing any material slipping of the portion coiled in the groove.

Some modifications may be made inthe construction shown and the device still be within the limits of my invention. For example, the means for preventing the rotation of the disks 1 and 2 with reference to each other may be different, the screw 5 may have a non-circular shank, and the plate 3 act as a nut; or the screw may be replaced by a rivet, and the plates 1 and 2 may be provided with surlaccs not smooth, or may have portions removed.

leaving a series of arms.

I. am aware that it is not broadly new to combine in a bag-tie two plates adapted to receive between them one end of the cord to be secured. The construction shown and depassing through and rigidly connecting the scribed herein is, however, materially difl'erplates 1 2 and engaging the plate 3, substanent from any prior form with which I am aetiallyas shown and described, and for the 15 quainted, the essential novelty of my device purpose set forth. 5 beingindieated by the following claims. In testimony whereof I have signed this I claimspecification in the presence of two subscrib- 1. The combination of the disks 1 2, having ing witnesses.
